[(124 - x) ÷ 15 + 32] ÷ 8 + 28 = 33
[(124 - x) ÷ 15 + 32] ÷ 8 = 33 - 28
[(124 - x) ÷ 15 + 32] ÷ 8 = 5
(124 - x) ÷ 15 + 32 = 5 × 8
(124 - x) ÷ 15 + 32 = 40
(124 - x) ÷ 15 = 40 - 32
(124 - x) ÷ 15 = 8
124 - x = 8 × 15
124 - x = 120
x = 124 - 120

Răspuns:
Explicație pas cu pas:
[(124 - x) : 15 + 32] : 8 + 28 = 33
[(124 - x) : 15 + 32] : 8 = 33 - 28 = 5
(124 - x) : 15 + 32 = 5*8 = 40
(124 - x) : 15 = 40 - 32 = 8
124 - x = 8*15 = 120
x = 124 - 120 = 4
